Mega Man Zero 3, known in Japan as Rockman Zero3 (ロックマンゼロ３ Rokkuman Zero Surī) is the third game in the Mega Man Zero series for the Game Boy Advance. The game was developed by Inti Creates and published by Capcom in 2004.

This game follows almost exactly the same rules as its predecessor, Mega Man Zero 2. Once again, Zero has his Z-Saber, Buster Shot, and Shield Boomerang. However, Zero's rod weapon (originally the Triple Rod in Mega Man Zero and the Chain Rod in Mega Man Zero 2) has been replaced with the Recoil Rod: a pair of tonfa-like weapons that can be aimed in all directions. When charged up, a powerful stabbing attack is performed, which can knock enemies back, or propel Zero into the air if aimed down to the ground, like a makeshift pogo stick.

Zero also no longer needs to "level up" in order to obtain new weapon abilities (such as combos or the ability to charge attacks).
